HWCCT storage test doesn't create output

[pauler]

Hi @all,

I executed today the SAP HANA HWCCT test to verify the storage KPIs of a customer. The test ran through smoothly but there weren't any outputfiles created in the report_<testname>_<date>/DISK directory.

Version: 1.00.122.01.1470046197

storage.json:

{

"report_id":"Storage_Test",

"use_hdb":false,

"blades":["correcthostname"],

"tests": [{

            "package": "FilesystemTest",

            "test_timeout": 0,

            "id": 1,

            "config": {"mount":{"correcthostname":["/hana/data"]

                                },

                        "duration":"long"

                      },

            "class": "DataVolumeIO"

        },

  {

            "package": "FilesystemTest",

            "test_timeout": 0,

            "id": 2,

            "config": {"mount":{"correcthostname":["/hana/log"]

                                },

                        "duration":"long"

                      },

            "class": "LogVolumeIO"

        }

]

}

screen output:

correcthostname:/tmp/hwcct # source envprofile.sh

correcthostname:/tmp/hwcct # ./hwval -f exampleprofiles/singleNode_to_storage_test_cf                                                                                             g.json  -V

Does anyone have an idea why there are no outputfiles with the measured KPIs?

thanks heaps

Hi Paul,

I met the same situation, no file can be found in DISK directory. But if I run the landscape test, I can find output from the LINUX directory. Maybe a bug?

I am using HWCCT_122_1-20011536.SAR

Hi Johnny,

I was able to figure out the reason. The FilesystemTest.py had to be changed with the latest file from note: "2161344 - HWCCT patch note" even when the HWCCT archive was more recently released than the note.

best regards

Robert

Dear All,

I have had encountered this issue, same, no output from DISK folder.

Same as what Robert did.

Any findings?

Hi Wilbert,

Please check my marked answer. I was able to produce the fsperf output after I changed the FilesystemTest.py

best,

Hi Robert,

Is your hostname correcthostname? if not, replace it with the real hostname.

You'd better add <SID> for data and log volumes.

Check note 1943937 - Hardware Configuration Check Tool - Central Note with latest multiNode_to_storage_test_cfg_template.json / singleNode_to_storage_test_cfg_template.json version.

You'd better to extract HWCCT.SAR into directory /hana/shared/hwcct, then the result is is located under /hana/shared/hwcct/report_<report_id>_<timestamp>/DISK

Hi Ning,

thank you for the feedback. I changed the hostname just for the SCN. The hostname in the .json file is set to the correct one. I also used the latest .json file from the SAP note.

IMHO the path of the directories and extraction path does not matter in this case. Nevertheless I changed them as mentioned but still no output.

regards,

Robert

Hi Robert,

Sorry, from my side, I do not why it looks like that.

As a workaround, can you try to use Fsperf for file system test as mentioned in SAP HANA HW Configuration Check Tool 1.9 -> 2.3 FilesystemTest for SPS10.

Ning
